Application Number: 00107228Application Date: 2000.04.29Publication Number: 1321728Publication Date: 2001.11.14Priority Information: International: C07C15/00;C10G70/02Applicant(s) Name: Chine Petro-Chemical Corp.Address: Inventor(s) Name: Lin Jie;Zhang Guochao;Feng QiPatent Agency Code: 72001Patent Agent: xu shuAbstract The method for aromatization of light hydrocarbon includes the process of that under the condition of making aromatization reaction, making the gas raw material of C1-C5 mixed hydrocarbons produce contact reaction with an aromatization catalyst. The composition of said catalyst is comprised of (by wt.%) Zn 0.8-3.5%, mixed rare earth oxides 0.2-1.5 % and carrier 95.0-99.0%, in which the carrier is formed from 50-80 % of HZSM-5 zeolite and 20-50% of gamma-alumina, and the mixed rare earth oxides contain 20-40% of lanthana, 40-60% of cerium oxide, 10-18% of praseodymium oxide and 2-10% of neodymia. Said method is specially applicable to production of arene and hydrogen gas by using low-pressure gas of refinery.
